Test Data Generator — Fake Credit Card & IBAN
Generate Luhn-valid fake credit card numbers and checksum-valid IBANs for QA testing and form validation — clearly synthetic, never real accounts.
Why generate fake test data?
QA and development environments regularly need realistic-looking input to exercise form validation, Luhn checks, payment UI states and database constraints — without touching real payment networks or real bank data. This tool generates numbers that satisfy the same checksum algorithms real card numbers and IBANs use (Luhn and ISO 7064 mod 97-10 respectively) but carry no real-world association.
Frequently Asked Questions
Can these card numbers be charged?
No. They pass the Luhn checksum (the same basic format check every card number must satisfy) but are not issued by any real bank, so any real payment processor will decline them immediately.
Are these the same as official payment-gateway test cards?
Not necessarily — Stripe, PayPal and other processors publish their own specific test numbers that their sandbox recognizes. Use this tool for generic format/Luhn validation testing, and your payment provider's official test cards for sandbox transaction testing.
Is the IBAN checksum really valid?
Yes — it's computed using the real ISO 7064 mod-97 algorithm that all IBANs use, so it will pass any IBAN format/checksum validator. The bank and account portion is random and not tied to a real institution.
